How is it that the sun makes us feel good?

I’m ignorant here but I’m sure there are physiological reasons; warmth, light, vitamin creation etc., but also psychological and emotional reasons.

I’ve just been looking out the window at a sun drenched plaza.  People are sitting on steps, eating, drinking, standing, chatting, walking purposefully. The trees are showing their first signs of bud. The colours on the brick built cathedral stunning. The shadows evocative. The light glorious. The mood inviting.

I’m inside.  I can’t feel the warmth; the sunlight isn’t landing on me directly and the sun isn’t being overly energetic with any chemical in my body… and yet just gazing at the scene makes me feel good.  Bring me sunshine…

Eric and Ernie were right.
